SOLE-PRESSYING MACHINE.

SPECIFICATION forming part of Letters Patent No. 393,215, dated ovember 20, 1888.

Application filed July 14, IE BB. Serial No. 279,988. (No model.)

To all whom it may concern,-

Be it known that I, FREDERICK W. GoY, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and 5 useful Improvements in Sole-Pressing Machines, of which the following is a specification.

This invention has for its object to provide a simple and convenient machine whereby boot and shoe soles may be molded or beaten out between male and female dies of appropri-' ate form; and it consists in the several improvementswhich I will now proceed to describe and claim.

: Of the accompanying drawings, forming a part of this specification, Figure 1 represents a side elevation of my improved machine. Fig. 2 represents afront elevation of the same. Fig. 3 represents a section on line x 00, Fig. 2.

Figs. 4 and 5 represent perspective views of parts of the machine in different positions. Figs. 6 and 7 represent, respectively, sections on lines 3 y and z 2, Fig. 1. The same letters of reference indicate the same parts in all the figures.

In the drawings, a represents the 'support ing frame or base, from which rise vertical guide-rods b. Fitted to move on said guiderods are carriers 0, which support the lasts or 0 formers d. Ihave here shown two lasts or formers d and supporting-carriers 0; but it will be remembered that in an organized machine there may be any desired number of lasts-as many in fact as can be conveniently attended to by one or more operators-each last being operated independently by mechanism hereinafter described.

e 6 represent the sole-forming dies, which are supported by a head, f, affixed to the up- 40 per ends of the uprights b, said dies being in position to cooperate with the lasts or formers 12. Each die 6 is adapted to rock or tip slightly, either lengthwise or crosswise, to enable it the better to conform to the bottom of 5 the last or former d, as usual in machines of this class.

The mechanism whereby each carrier and the last or former thereon are operated is as follows: Fitted to slide on the guide-rods [1, un-

der the carrier 0, is a cross-head, g, which is supported by links it h, constituting a togglejoint, the upper links h being pivoted to said cross-head, while the lower linksh are pivoted at-z' to a standard or lug affixed to the base a. The meeting ends of said links are 5 5 connected by a rod,j, with a slide, it, which is adapted to move in fixed guides, and is provided with a trundle-roll, Z, entering a camgroove, 71, in a wheel, 0, affixed to a shaft, 1). The rotation of saidshaft, effected by means 6 presently described, reciprocates the slide and thereby causes the latter to alternately force the toggle-links h h into and out of alignment, and thus raise and lower the cross-head g and with it the carrier c and its last or former d. 6 The carrier 0 is movable on the guide-rods independently of the cross-head, so that although it is raised by the upward movement of the cross-head it is capable of being more rapidly raised by preliminary lifting devices, hereinaf- 7O ter described,which act before the toggle-joints to lift the last or former and bring the sole thereon into contact with the die, thereby holding the solein position between the former and die before the molding pressure isimparted by the action of the toggle-joints. The said preliminary lifting devices are, first, a sleeve, q, fitted to slide vertically on a guide-rod, r, Fig. 3, affixed to the cross-head 9, said sleeve bearing at its upper end against an adjustable s screw, s, which works in a threaded socket in the carrier 0; secondly, a slide, 15, fitted to move 'in vertical guides u u on the cross-head 9,

said slide having a yielding rod, 1), which bears against a flange, a, on the sleeve q, and 8 is supported by a spring, to; and, thirdly, a cam, b, on the shaft 19, arranged under the slide If, its perimeter supporting a roll, a, on said slide.

' The rotation of the cam b when the roll 0 0 rests in the depression of the cam, as shown in Figs. 1, 2, and 4, causes the cam to raise the slide t, sleeve q, and former carrier 0, the former being thus rapidly raised until the concentric portion of the cam b supports the roll 5 c, as shown in Figs. 3 and 5. The movement thus imparted to the former brings the sole thereon into contact-with the die 6 before the toggle-links h h raise the cross-head, the cam b being timed to operate, as described, before too the cam-grooven moves the slide 76 to straighten the toggle-links. After the former has been raised by the cam b, it is supported by the concentric portion of the latter while the crosshead 9 is being raised by the toggle-links. The carrier 0 may be adjusted vertically by the screw 8, the latter resting on the sleeve q, and raising the carrier when turned in one direction and lowering it when turned in the opposite direction. Provision is thus made for bringing the sole-supporting surface of the former into the proper relation with the die by the action of either the cam b or the toggle links, so that variations in the sizes of formers and dies and in the thickness of soles may be compensated for. The rod 22, which communicates the upward movement of the slide it to the sliding sleeve q and carrier 0, is

enabled by the spring 10 to yield when the former has come to a sufficiently firm bearing on the sole between it and the die, thus preventing undue Strain n friction on the cam b in case the latter has not completed the upward movement of the slide it.

To enable the extent of upward movement imparted to the former d by the cross-head g to be adjusted, I provide the upper end of said cross-head with two inclines, d d, and form on the sleeve q, which slides in said socket, two wings or lugs, e e, which may be turned so as to rest on said inclines at any desired points. The flange a of the sleeve q is provided with a handle, f, whereby the operator may turn the sleeve q, so as to cause its lugs e to rest on the desired portions of the inclines d. It will be seen that by turning the sleeve q so as to move its lugs toward the higher ends of the inclines the sleeve and the carrier and former supported thereby will be raised; but when the sleeve is turned in the opposite direction it will be depressed with the carrier ahd former. The cross-head g is provided with vertical slots h between the inclines d cl, which slots are formed to receive the lugs e, and thus permit the sleeve 1 to be depressed. The inclines d and rotary sleeve q, with its lugs e, furnish a means whereby the operator may quickly adjust the former so as to accommodate its pressing-surface to the thickness of the sole, said devices operating more quickly than the adjusting-screw s, which is designed only for such adjustments as are made necessary by changes in the sizes of forms and dies.

'6 represents the driving-shaft which communicates motion to the shaft 1) through a worm, j, on said driving-shaft and a wormwheel, k, on the shaft 1). Said worm-wheel is loose on the shaft 1), and is made operative by a sliding clutch,l,which rotates with the shaft p and engages with a clutch, m, on the hub of the worm-wheel. The sliding clutch is normally held in contact with the clutch m by springs 0, Fig. 3, and is separated from the clutch m to make the worm is inoperative by a pin or stud, p, which normally stands in position to act on inclines g on the flange 1- of the sliding clntch,and thereby move the clutch back out of engagement with the worm-wheel. One of said inclines comes in contact with the pin p when the former is fully raised by the toggle-links and the other incline acts on the pin when the former is depressed. The pin 19 is normally held by a spring, 8', in position to act, as described, on the sliding clutch. .A treadle, t, and intermediate lever, a, operated thereby'are provided, whereby the operator may depress the pin 12, and thus release the sliding clutch and permit its springs to force it against the clutch m of the wormwheel.

The clutch above described and the means for operating it are old and well known; hence I have not deemed a minute description thereof necessary.

The operation is as follows: The cross-head g and carrier 0 and former d being depressed and the cam b in position to support the slide tin a depressed position, the operator, after placing a sole on the former,releases the clutch Z by depressing the treadle t and pin 1). The clutch at once engages the continuously-rotating clutch m on the worm-wheel 7c, and the shaft 10, with its cams n I), is rotated, the cam b acting first and raising the slide t and former d, as already described, after which the cam or acts to force forward the slide in and throw the links h h into alignment, the molding pressure being thusimparted to the former. \Vhen the toggle-links are in line with each other, and the former d is in its highest position, the pin 1), acting on one of the inclines q of the sliding clutch, withdraws the sliding clutch from the worm-wheel clutch,so that the former cl remains in its pressing position as long as the operator desires. When the pressure on the sole has continued long enough,the operator again depresses the treadle t, whereupon the sliding clutch is again engaged with the worm-wheel clutch, and the shaft 10 is again rotated until the toggle-operating slide is is drawn fully back and the cam supported slide i is fully depressed, when the movement of the shaft 12 is again stopped,as before,by the automatic disconnection of the clutch Z from the clutch m, the former d being thus kept depressed while the operator is removing the formed sole and applying another, after which the shaft 1) may be again set in motion, as before.

The organized machine is provided with a series of formers, d, and dies 0, and an independent mechanism, such as is above described, to operate each former, there being a shaft, 19, cam I), and the described intermediate devices for each former.

The driving-shaft t" imparts motion to the worm-wheels of all the shafts p in the machine, said driving-shaft having a series of worms, j, meshing with the worms 7c of the shafts p, as shown in Fig. 6. Each shaftp is provided with a sliding clutch, Z, as shown in Fig. 7, and each sliding clutch is normally held in contact with the clutch mon the corresponding worm-wheel by springs 0, arranged as shown in Fig. 3, and separated from said clutch" 4 m by a pin or stud, 1), arranged and operating as hereinbefore described. A treadle, t, and intermediate lever, it, operated thereby are provided for each pin or stud 1), so that the operator may depress either pin 1), and thereby release either sliding clutch and permit its springs to force it into engagement with the corresponding clutch of the worm-wheel. It is therefore within the power of the operator to put any shaft 1) in operation at will, and thereby operate each former independently, so that while one former is held in its highest position by the disconnection of its operatingshaft 1) from the driving-shaft 2', another former may be held in its lowest position to permit the application of a sole, and another may be moving toward or from its pressing position, so that the operator, after applying a sole to a former, d, and attending to its preliminary presentation to the corresponding die 6 by the cam I), may leave it and attend to another former while the molding pressure is being applied and maintained. One operator can therefore attend conveniently to several formers.

The supporting-screw s of the carrier 0 has a hand-wheel, 8', whereby it may be conveniently rotated.

It is obvious that the screw s may be omitted, in which case the carrier 0 might bear directly on the sleeve g.

If desired, the former may be supported directly by the cross-head said cross-head being in such case the former-carrier.
